PHP array to object, object to array

Not much nonsense, go directly to the code:

<?php
class object_array{
    //数组转对象
    public static function array_to_object($e){ 
        if(gettype($e)!='array') return; 
        foreach($e as $k=>$v){ 
            if(gettype($v)=='array' || getType($v)=='object') 
                $e[$k]=self::arrayToObject($v); 
            }
        return (object)$e; 
    }
    //Object to array 
    public  static function obj_to_array($e){
        $e=(array)$e; 
        foreach($e as $k=>$v){ 
            if(gettype($v)=='resource') return; 
            if(gettype($v)=='object' || gettype($v)=='array') 
            $e[$k]=self:: get_array($v); 
        }
        return $e; 
    }
}
